You are as young as your self-confidence, as old as your fears; as young as your hope, as old as your despair.
Maturity is the ability to think, speak and act your feelings within the bounds of dignity. The measure of your maturity is how spiritual you become during the midst of your frustrations.
Nobody grows old merely by living a number of years. We grow old by deserting our ideals. Years may wrinkle the skin, but to give up enthusiasm wrinkles the soul.
When the wires are all down and your heart is covered with the snows of pessimism and the ice of cynicism, then, and only then, have you grown old.
In the central place of every heart, there is a recording chamber; so long as it receives messages of beauty, hope, cheer and courage, you are young.
Worry, fear, self-distrust bows the heart and turns the spirit back to dust.
Youth is not a time of life; it is a state of mind; it is not a matter of rosy cheeks, red lips and supple knees; it is a matter of the will, quality of the imagination, a vigor of the emotions; it is the freshness of the deep springs of life.
Youth means a temperamental predominance of courage over timidity of the appetite, for adventure over the love of ease. This often exists in a man of sixty more than a body of twenty. Nobody grows old merely by a number of years. We grow old by deserting our ideals.
When the aerials are down, and your spirit is covered with snows of cynicism and the ice of pessimism, then you are grown old, even at twenty, but as long as your aerials are up, to catch the waves of optimism, there is hope you may die young at eighty.
Youth is not a time of life – it is a state of mind.
Whether seventy or sixteen, there is in every being’s heart a love of wonder; the sweet amazement at the stars and starlike things and thoughts; the undaunted challenge of events, the unfailing childlike appetite for what comes next, and the joy in the game of life.
